The mode of action of non-steroidal inhalers is not completely understood. These non-steroidal alternatives are considered to be less effective preventer therapies but they may be of value in treating allergic asthma.
There are two alternative non-steroidal preventer inhalers available; one is called Intal (sodium cromoglicate) CFC-free 5mg Metered Dose Inhaler (MDI) and the other is called Tilade (nedocromil sodium) CFC-free 2mg MDI. These medications need to be taken up to three or four times a day on a regular basis and this may be difficult to adhere to. Another factor for consideration is that Tilade (nedocromil sodium) has been reported to have a particularly bitter taste and for some people this unpleasant taste, may result in poor compliance.
Intal Spincaps (sodium cromoglicate) which came in a dry powder form and was used with a Spinhaler Insufflator have been discontinued. The Intal CFC-free MDI was introduced in September 2008 to replace this.
